An air nozzle is positioned immediately adjacent to each roller for cooling the entire width of a web as the web is heated to accomplish the melting of the predetermined necessary fibers without adversely affecting other fibers in the web.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to techniques for manufacturing woven and non-woven textile products such as a carpet fabric, and more particularly to a method and apparatus for fusing the back, front or both sides of woven or non-woven fabrics by fusing the surface on underlying areas with a controlled flame from a burner as a heat source.

2. Description of Related Art

Heat activated thermoplastic yarns have been used in the cuff edge of a glove for binding the cuff edge when heat activates the thermoplastic yarns and melting occurs as described in U.S. Pat. No. 4,842,611. Also, U.S. Pat. No. 4,488,928 discloses bulky absorbent webs are formed if bonded by heating low melt thermoplastic fibers of the web.

Traditionally carpet fibers or non-woven webs either synthetic and/or various blends (including cellulose) are stabilized by using latex and/or other products to achieve the same purpose. Closing pores in a fiber web can result in using less latex or stabilizing material which results in a cost savings to the web manufacturer.

Automotive and some other carpets use a blend of a low melt and poly fibers, and in order to lock or fuse the fibers after being mechanically bound by a needle-punching process. The web runs through specialized ovens in order to melt the more expensive low melt fiber and lock or fuse the poly-fibers within the web.

SUMMARY OF THE INVENTION

Accordingly, it is therefore an object of this invention to provide a method and apparatus for producing less expensive non-woven fabric made from a combination of synthetic or blend of synthetic and natural fibers without low melt fibers or binders, by melting or fusing one or more surfaces with a flame or high heat burner heat source.

It is another object of this invention to increase the tuft bind and elongation of a non-woven fabric such as a carpet by melting one or more surfaces of the fabric.

It is yet another object of this invention to eliminate and/or reduce the amount of latex or other backing materials on a fabric such as a carpet, and therefore, reduce the cost of making such carpet.

It is another object of this invention to provide a method of fiber locking of a textile web or carpet by the application of a flame or high heat to melt the synthetic fibers, that the web is made of without the need of low melt fibers or any other binders on the back, front or both sides of the textile web or carpet.

It is another object of this invention to provide a method of fiber fusing that can be performed in line with a needlepunch machine for the production mechanical binding, the method not limited to eliminating the need for the handling of the web by a second process of latex binders, which saves labor costs and energy.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENT

Referring to FIG. 1, a schematic representation is shown of a side view of an apparatus 10 for fiber fusing and fiber locking one or more sides of a web 12 of woven or non-woven fabric according to the present invention. The non-woven fabric may be produced from synthetic and/or some blends of synthetic and natural fibers that may or may not be mechanically bound together by a needlepunch process. The web 12 of a fabric comprises a synthetic and/or blend of synthetic and natural fibers. In addition, the web fabric may include a flame retardant fiber and/or an antimicrobial fiber. The apparatus 10 melts the exposed and predetermined percentage of fibers in the web 10 with burners 20, 22 having an open flame 21, 23 or high heat output which results in increasing the tuft bind and elongation of the web of non-woven fabrics, such as a carpet. The web 12 of a non-woven fabric or another article after passing through apparatus 10 results in a product that has a strong melted backing composition which exhibits excellent dimension stability, strong bonding to the web substrate and low resistant tack. The apparatus 10 results in eliminating or reducing the amount of latex or other similar bonding materials used in the prior art because of the synthetic fibers and/or some blends and natural fibers melting ability.

Still referring to FIG. 1, a small diameter directional roller 14 guides the web 12 from a mechanical binding apparatus such as a needlepunch loom or from an unwind stand if the fiber locking is a separate process with a product roll (not shown) directed toward a water cooled roll 16, and then the web 12 passes around a portion of the roll 16. The rolls 16, 18 can be turned by the friction of the web 12 or turn assisted by a drive commonly know in the art. Positioned on the left side of roll 16 is a first burner 20 which extends across the face of the roll 16 and emits a flame or high heat directed to the web 12. A second water cooled roll 18 is positioned below and to the right of roll 16, and the web 12 passes around a portion of roll 18 after leaving roll 16 and then exits the apparatus 10 via a guide roller 24 to a product take-up roll of a winding machine (not shown). Positioned on the right side of roll 18 is a second burner 22 which extends across the width of web 12 and emits a flame or high heat directed to the web 12 as it passes around a portion of roll 18. The first burner 20 is turned on to heat and melt fibers on a first side of the web 12, and the second burner 22 is turned on when required to heat and melt fibers on a second side of the web 12. First burner 20 and second burner 22 may both be turned on simultaneously or only one of then may be turned on depending on requirements for the fabric being processed. The burners 20, 22 may be embodied by Part No. 329 with sheet ribbon assembly 9RV/4F manufactured by Ensign Ribbon Burners, LLC of Pelham Manor, N.Y. 10803. The water cooled rolls 16, 18 may be embodied by Part No. SSR-35 manufactured by WEBMAN of South Carolina of Mayo, S.C.

A first air nozzle 26 is positioned adjacent to the roll 16 aimed at the surface of the web 12 that touches the roll 16. The air nozzle 26 extends across the face of the web 12 in order to cool the surface of the web 12 that is not treated by the burner 20. The use of the air nozzle 26 is to avoid the chance of distortion (melting and/or flattening) of the non-treated (at the time) side of the web, regardless of the amount of flame needed at the time for the fiber-locking process of the web 12.

The air nozzle 26 is mounted by bolting it on the sides (walls) 11 of the apparatus 10. The source of air is supplied by a fan, blower or compressed air from both sides of the nozzle or just one, depending on the width of the apparatus 10.

Likewise, a second air nozzle 28 is positioned adjacent to the roll 18 aimed at the surface of the web 12 that touches the roll 18. The air nozzle 28 extends across the face of the web 12 in order to cool the non-treated side of the web 12 in case the amount of flame 23 from the burner 22 has to be increased to a higher required level for treating the web running at the time. The 329 w/sheet ribbon assembly 9RV/4F delivers a maximum of 2,800 BTU's in/hr and a minimum of 700 BTU's in/hr. Typical automotive carpet requires for fiber fusing, that the apparatus 10 operates at 20 F.P.M. and approximately 2,200 BTU's in/hr. These operating numbers change depending on the web's speed, type of fiber and amount of fiber locking required. The air nozzle may be embodied by Part No. ANZ-37 manufactured by WEBMAN of South Carolina of Mayo, S.C.

Referring to FIG. 2, a schematic representation is shown of a side view of an apparatus 30 for fiber fusing a fabric. Apparatus 30 comprises the same elements as apparatus 10 in FIG. 1 having the same reference numbers, with the addition of a first blade 32 positioned immediately after the web 12 leaves roll 16, and a second blade 34 positioned immediately after the web 12 leaves roll 18. The first blade 32 is movable about an end 42; in an operating mode, the first blade 32 is positioned by an arm 44 so that it touches the web 12, which is illustrated in FIG. 2 by dashed lines 32a, and flattens the melted fibers on the surface of the web 12 and produces bonding of more fibers. In a standby mode or threading mode, the first blade 32 is moved away from the roll 16 thereby allowing a web 12 to be removed from apparatus 30 or a new web inserted therein. Likewise, the second blade 34 is movable about an end 43; in an operating mode, the second blade 34 is positioned by an arm 45 so that it touches the web 12, which is illustrated in FIG. 2 by dashed lines 34a, and flattens the melted fibers on the surface of the web 12 as well as bonding more fibers together. As shown in FIG. 2, a first blade 32 touches one surface of the web 12 and when required, the second blade 34 touches an opposite surface of the web 12. In a standby or threading mode, the second blade 34 is moved away from the roll 18. Gap adjusting elements 46, 47 may be added to the apparatus 30 to establish fixed gaps for the web 12 to pass by the blade 32 and 34 for the fiber fusing of certain fabrics such as automotive carpet which needs a gap of 0.187 inches. A flat steel bar (not shown) holds the gap adjusting elements 46, 47, and is welded on the wall 31 of the apparatus 30. The pivot point of the blades 32 and 34 are welded on the wall 31 of the apparatus 30. The blades are made out of steel and Teflon coated, if needed, and the arm is made of steel. If floating blades 32 and 34 are preferred, the gap adjusting elements 46, 47 are removed. The blades 32, 34 may be embodied by Part No. BL-32 manufactured by WEBMAN of South Carolina of Mayo, S.C.

Referring to FIG. 3A and FIG. 3B, FIG. 3A shows a graphical representation of an unprocessed web fabric 50, having upper and lower surfaces which are not yet processed by the present invention. FIG. 3B shows a graphical representation of a processed web fabric 52 having upper surface 54 and melted fibers on a lower surface indicated by round balls 56 according to the present invention. The effect produced by the melted fibers or round balls 56 is eliminated by the blades 32 or 34 which flatten the round balls 56 on the surface of the web fabric 52 that either blade 32 or 34 contacts.

Referring to FIG. 4, a schematic representation is shown of a side view of an alternate embodiment identified as apparatus 40 for fiber fusing a fabric web 12 having an assembly comprising cylindrical rolls 36, 38 for flattening melted fibers. The apparatus 40 comprises the same first and second water cooled rolls 16, 18, the same first and second burners 20, 22 and the same first and second air nozzles 26, 28, as described above for apparatus 30, but instead of blades 32, 34, apparatus 40 comprises the assemblies of first and second cylindrical rolls 36, 38. The cylindrical rolls 36, 38 pivot about ends 37, 39 respectively and steel arms 47 and 49 move the cylindrical rolls 36, 38 from a standby mode or a thread-up mode to an operating mode, which is illustrated in FIG. 4 by the dashed lines 36a and 36b, where they are able to flatten the melted fibers on a surface of the web 12. Gap adjusting elements 46, 47 may be added to the assemblies of cylindrical rolls 36, 38 to provide a fixed gap depending on the thickness of the web 12 to enable the web 12 to pass by the cylindrical rolls 36, 38 for the fiber fusing of certain fabrics such as outdoor carpets, synthetic upholstery, but not limited to them. If floating cylindrical rolls 36, 38 are preferred, the gap adjusting elements 46, 47 are removed.

The method of fiber fusing a fabric employing the apparatus shown in FIGS. 1, 2, and 4 is provided for binding the back, front or both sides of woven, non-woven, either horizontally or vertically lapped, textile products primarily for but not limited to carpets, by melting the surface or underlying area with a flame or high heat source provided by burners 20 and 22. This method creates a textile product having unique and very strong backing which exhibits excellent dimensional stability, strong bonding to the substrate and low residual tack (not sticky) after the product has cooled off.

In addition, this method provides a melted composition which is more easily processed than polyurethane forming compositions which are conventionally employed to prepare textile backings and which provide the desired dimensional stability, tack and adhesion. The use of the external heat source such as burners 16 and 18 which provides both exceptional tuft and elongation also improves crack resistance of the created backing. The method eliminates the traditional approach to stabilize carpet fibers, woven or non-woven webs, either synthetic (man made) and/or various blends (including cellulose) using latex and/or other products to achieve the same purpose.

This method also encompasses the ability to vary the degree of fiber locking by increasing or decreasing the flame 21, 23 providing high heat or by guiding the web 12 around various diameter rolls such as 8″, 6″, 5″, and 4″, but not limited to these sizes, depending on the web's width. In an alternate embodiment, the rolls 16, 18 may be replaced with bars, if the friction and tension on the web 12 can be tolerated. Thus, the smaller the diameter of the roll the web 12 travels around, the web 12 becomes more open and allows an increase in the amount of flame or heat to penetrate the fibers of the web 12. In addition, the speed the web 12 travels through the apparatus 10, 30, and 40 may be used to adjust the amount of fiber fusion.

On various blends of synthetic fibers and natural fibers, the method using the apparatus 30, 40 in FIG. 2 and FIG. 4 creates the desired backing by melting the synthetic fibers and then passing the web 12 through a nip or gap with a smooth or textured cylindrical roll 36, 38 while the web fabric is still hot in order to totally flatten and bond the natural fibers with the melted synthetic fiber.

The method of fiber fusing a fabric web 12 comprises the steps of:

• • (a) providing the fabric web 12 to a first water cooled roll 16;
  • (b) threading the web 12 around a portion of the first water cooled roll 16 (or a stationary bar if web's tension allows it) and between the roll 16 and a first blade 32 under the roll 16 for flattening melted fibers;
  • (c) threading web 12 around a portion of the second water cooled roll 18 (or a stationary bar if web's tension allows it) and between roll 18 and a second blade 34 under roll 18 for flattening melted fiber, of said fabric web 12 being processed;
  • (d) positioning a first burner 16 aimed at the web 12 as it goes around a portion of the first roll 16 to apply a predetermined flame or heat to the web 12, according to a particular fabric web 12 being processed;
  • (e) positioning a second burner 22 aimed at the web 12 as it goes around a portion of the second roll 18 to apply a predetermined flame or heat to the web 12, according to said particular fabric web 12 being processed;
  • (f) positioning a first air nozzle to cool the web 12 as the web 12 contacts the first roll 18, as required for the particular fabric web 12 being processed; and
  • (g) positioning a second air nozzle to cool the web 12 as the web contacts the second roll 18, as required, for the particular fabric web being processed.

The above method enables various types of fabric webs to undergo fiber fusing on one or more sides, at various speeds and at various heating temperatures as required to accomplish the correct amount of fiber fusing. For example, when a fabric web 12 requires fiber fusing on only one main surface, only one of the burners 20, 22 will be ON, and only the blade associated with the ON burner will be touching the web 12. When a fabric web 12 requires fiber fusing on two opposite surfaces, then both burners 20, 22 will be turned ON and both blades 32, 34 will be touching the web 12 for flattening the melted fibers after the web 12 passes each burner 20, 22.

This invention has been disclosed in terms of certain embodiments. It will be apparent that many modifications can be made to the disclosed apparatus without departing from the invention. Therefore, it is the intent of the appended claims to cover all such variations and modifications as come within the true spirit and scope of this invention.
